A Mosquito-Borne Threat: Protecting Our Communities from Ross River Virus
In the heart of Gosnells and Canning, a silent battle against mosquito-borne illnesses is underway. The Ross River virus, a persistent concern, has prompted local authorities to take action and raise awareness among residents.
Dr. Andrew Robertson, Chief Health Officer at the Department of Health, emphasizes the prevalence of Ross River virus (RRV) across Western Australia. "RRV is an ever-present threat, with case numbers fluctuating annually," he warns.
But here's where it gets controversial: while the virus is widespread, the number of cases varies significantly between regions. Gosnells and Canning have recorded six and five cases, respectively, over the 2021-25 period. Compare this to Armadale and Serpentine Jarrahdale, which saw eight and six cases during the same timeframe.
The City of Gosnells is taking proactive measures during the 2025-26 mosquito season. They're monitoring mosquito activity and applying treatments at identified breeding sites. Ian Cowie, CEO of the City of Gosnells, urges residents to follow the Department of Health's guidelines:
"Cover up, repel, and clean up! Wear long, loose-fitting clothing, use insect repellents with DEET or picaridin, and eliminate standing water around your home."
In Canning, the presence of the Canning River creates ideal conditions for mosquito breeding, especially in tidal areas. Salt marsh mosquitoes, like Aedes vigilax and Aedes camptorynchus, are known for their aggressive biting behavior and potential to transmit diseases, including Ross River virus.
"We can't ignore the low but consistent numbers of Ross River virus cases in our district," says a spokesperson for the City of Canning. "That's why we've implemented a comprehensive Mosquito Management Program to tackle breeding, reduce adult mosquito populations, and minimize disease risks."
The program involves inspections and treatments of mosquito larvae, regular trapping to monitor adult mosquito numbers, tide and storm surge monitoring, stormwater drain maintenance, and ongoing community education. The City of Canning also encourages residents to report increased mosquito activity and take precautions when spending time outdoors.
So, what's your take on this? Are these measures enough to tackle the Ross River virus threat? Or do we need more innovative solutions? Share your thoughts in the comments below!
